Hello, I have a question about redistributing charges. If you have three identical spheres: A is -2 uc (microcoulombs), B is -6 uc, and C is +5 uc, touch A and B together, separate, then touch B and C together, and separate, with what charge does C end up with? I don't understand how positive...
If the length of a string with two fixed ends and three loops, along with the wave speed is given, how would you find the lowest frequence for standing waves on that string? I thought that the fundamental frequency determined the lowest frequency. Thanks for your help!

(1) I don't understand how the wavelength of incoming waves affects the wavelength of the outgoing wave when it strikes a partial barrier. For example, in a ripple tank, the waves in the center hit a straight barrier, while those on the sides pass through.

What type of bumper, made only of one sheet of paper and masking tape, would be most effective in a collision between a wooden block and a 1 kg cart? I have experiment with several designs including cylinders, spring-like compression bumpers and square pyramids, but none seem to work very well...
Hi, I attempted this problem, but I do not see how it makes sense. Could somebody give me an idea of how to solve this problem? Thanks!
